App UI/UX Design Services
Design mobile and web apps that users love — research-led, accessibility-first, and handed off in Figma tokens that engineers ship without translation or guesswork.
Full-Cycle App UI/UX Design
We cover the complete design process — from user research and journey mapping to high-fidelity screens and a developer-ready design system. Every deliverable is built to survive the engineering hand-off.
Full-Cycle App UI/UX Design
We cover the complete design process — from user research and journey mapping to high-fidelity screens and a developer-ready design system. Every deliverable is built to survive the engineering hand-off.
- User research, personas, and journey mapping
- Information architecture and navigation design
- Wireframes, lo-fi, and interactive prototypes in Figma
- High-fidelity UI with a complete component library
- Motion and micro-interaction specification
- Moderated usability testing with target users
Mobile App Design Specialisation
We design for iOS (Human Interface Guidelines), Android (Material Design 3), and cross-platform — respecting each platform’s native conventions while maintaining a consistent brand identity across every screen.
- iOS HIG-compliant design patterns and gestures
- Material Design 3 for Android with dynamic colour
- Dark mode and high-contrast accessibility (WCAG 2.2 AA)
- Gesture-driven navigation and bottom-sheet patterns
- Onboarding flows engineered to reach first activation fast
- App Store screenshot design and metadata copy
Interaction Design & Motion
Static screens tell you what an app looks like — motion tells you how it feels. We design every transition, micro-interaction and feedback animation with a documented motion system so the final product moves with intention, not just decoration.
- Motion principles document (duration, easing, hierarchy)
- Micro-interaction design for buttons, inputs and loaders
- Page transition and navigation animation specs
- Lottie animation integration guidelines
- Skeleton loading and progressive reveal patterns
- Haptic feedback mapping for iOS and Android
Design Handoff & Developer Collaboration
Most design-to-code friction happens not in the design but in the handoff. We produce developer-ready Figma files with auto-layout, semantic tokens and component annotations — and stay in the sprint alongside engineers to answer questions before they become bugs.
- Auto-layout Figma components with constraint logic
- Semantic colour, spacing and type token export
- Zeplin / Figma Dev Mode annotation layer
- React + Tailwind design token package
- Storybook component documentation
- Weekly design–engineering pairing sessions
App Design Sprint & Rapid Prototyping
When speed matters — a new feature, a pitch, a pivot — we run a focused 5-day design sprint that goes from problem statement to tested prototype without the overhead of a full discovery phase. You get a validated concept you can take straight to engineering or investor demo.
- Day 1: Problem mapping and How Might We framing
- Day 2: Competitive review and concept sketching
- Day 3: High-fidelity Figma prototype build
- Day 4: Moderated usability testing (5 users)
- Day 5: Insight synthesis and refined prototype
- Full sprint report with next-step recommendations

Hand off
Tokens, components, dev partnership.
A SaaS redesign that lifted activation 47%.
Restructured information architecture, rebuilt the design system on tokens and shipped in tandem with the engineering pod — activation up 47%, support tickets down 31%.
The tools we ship with.
Design that survives the engineering hand-off.
The cost of design is not in the Figma file — it is in the rebuilds that happen when intent, accessibility and motion are lost in translation. We design with the build in mind, in tokens and components engineers can ship without re-interpreting.
Tokens, not screenshots
Colours, spacing, type scales and motion are defined as semantic tokens that map 1:1 to Tailwind variables and React props — so the dev team consumes the system instead of pixel-counting from a Figma frame.
Accessibility as a default
WCAG 2.2 AA is baked into the components themselves: focus rings, contrast ratios, reduced-motion variants and screen-reader semantics. Compliance becomes the path of least resistance, not a sprint at the end.
Motion with intent
Every animation has a job — confirming an action, communicating state, smoothing a transition. We document motion principles alongside type and colour, so the product feels considered everywhere, not just on the hero.
Research that ships work
We run lean weekly tests with five users, share clips with the squad, and ship the next iteration the following sprint. Insight stays close to delivery — not buried in a 60-page deck nobody re-opens.
How we make decisions.
AI-assisted code review
Static analysis + ML pattern checks on every PR.
Observability first
Logs, traces, RUM and alerts wired in from day one.
Outcome-tied KPIs

Discovery, mapping, prototyping and validation in two weeks — a tested concept you can take straight to engineering.
- User research + journey mapping
- Low-fi to hi-fi prototype
- Moderated usability testing
A production-ready Figma library paired with a versioned React component package — documented in Storybook.

Questions, answered.
Do you do design + engineering?
+
Yes. Designers and engineers ship in the same pod — Figma libraries map 1:1 to React + Tailwind component packages.
How do you handle research?
+
Moderated user testing, in-product analytics review and stakeholder interviews — weighted to the questions that move product KPIs, not just usability.
Will I get a design system?
+
Yes — tokens, primitives and patterns in Figma + a versioned React package. Documentation lives in Storybook.
Do you cover accessibility?
+
WCAG 2.2 AA is the baseline. axe-core in CI, plus manual screen-reader and keyboard tests on every release.
